Problem Description
The Actual Cycle


Neon, who works in a steam power plant, is asked to monitor
the performance of a new system. The new system
is running a Rankine cycle with water as the working fluid.
What is known:
 The Schematic of the new system is shown on the left. The design
data is:
Condenser Pressure: 10 kPa
Boiler Pressure:
16 MPa
Steam temperature at the turbine inlet: 600^{o}C
 The actual data measured by Neon are:
P_{1} = 9 kPa T_{1} =
38^{o}C
P_{2} = 16 MPa
P_{3} = 15.9 MPa
P_{4} = 15.2 MPa T_{4} =
625^{o}C
P_{5} = 15 MPa T_{5} =
600^{o}C
P_{6} = 10 kPa
 The pump has an efficiency of 85% and the turbine has an efficiency
of 80%.
 The mass flow rate is 20 kg/s.
